Blue Lake lighting is the use of blue laser excitation yellow fluorescent material to form a broad spectrum of white light, which is the core of laser lighting technology LBL content. As shown, the blue laser focuses on the phosphor crystal coating (PCC) and produces yellow fluorescence. The yellow light and the remaining blue light is not absorbed together to form white light. The emission spectrum is shown in Fig. As the yellow fluorescence for the broad spectrum of light, so the white light is also a broad spectrum of light, so there will be no color distortion and can not illuminate the object; this constitutes a laser light source is the ideal light source.
As the laser beam can focus on a very small point to stimulate the fluorescent material, so that all the white light are concentrated in this point out, LBL light source energy density close to the xenon lamp, is the ideal choice for special lighting source. The following table shows the LBL light source and LED light source and xenon light source of the key performance parameters of the comparison.
